Experimental Analysis of WLAN Security Weakness By Cracking 64 128 bit WEP Key

The IEEE-802.11 encryption technique Wired Equivalent Privacy (WEP) is still widespread used today despite the numerous discussions on its insecurity. This paper demonstrates the security flaws of WLAN by cracking 64, and 128 bit WEP key. A simple practical technique used for real time decryption of data packets after attack on WLAN access point, which gives an attacker opportunity for full access to the network is presented
